Khomeini Assumes Power as Iran Monarchy Falls

The Iranian Revolution against Shah Mohammad Reza Pahlavi had intensified after months of protests and strikes in 1978.

Nate Bargatze Born in Nashville

Nathanael Bargatze, known professionally as Nate Bargatze, was born on March 25, 1979, in Nashville, Tennessee. He began pursuing stand-up in Chicago and New York, developing a deliberately unhurried style rooted in family stories, everyday confusion, and understated reactions. Rather than relying on rapid punchlines or confrontational subjects, Bargatze often presents himself as a patient but bewildered participant in ordinary life. Albums, television appearances, podcasts, arena tours, and streaming specials brought that clean, conversational approach to a broad audience.

Egypt and Israel Sign Peace Treaty

Decades of conflict between Israel and its Arab neighbors, including major wars in 1948, 1967, and 1973, had left the Middle East deeply divided. Egyptian President Anwar Sadat's historic 1977 visit to Jerusalem broke diplomatic taboos and led to the Camp David Accords mediated by U.S. President Jimmy Carter in 1978. On March 26, 1979, Sadat and Israeli Prime Minister Menachem Begin signed the Egypt-Israel Peace Treaty at the White House, formally ending hostilities and establishing full diplomatic relations.

Three Mile Island Nuclear Accident Begins

At the Three Mile Island Nuclear Generating Station in Pennsylvania, a series of equipment failures and operator errors unfolded in the early morning hours.

Plant operators initially misread instruments and took actions that worsened the situation. By midday on March 28, 1979, radioactive gases had been released, prompting public concern and evacuations. The incident was contained without immediate fatalities, but it exposed critical flaws in reactor design, training, and emergency procedures. Investigations followed rapidly.

Iran Becomes an Islamic Republic

Following the 1979 Iranian Revolution that ousted the monarchy, Ayatollah Ruhollah Khomeini emerged as the dominant figure in the new revolutionary government. A national referendum was held to determine the country's political system amid competing visions among revolutionary factions. On April 1, 1979, Khomeini formally declared Iran an Islamic republic after the referendum showed overwhelming support. The declaration ended the Pahlavi dynasty and established a theocratic framework under the doctrine of velayat-e faqih, or guardianship of the Islamic jurist. It consolidated clerical authority over state institutions and foreign policy. The move marked the culmination of the revolution's transformation from a broad anti-monarchy coalition into an explicitly Islamic state.
